Useful Postprocessing Techniques Using the Graph Marker Tool

In this month’s Tips and Tricks video, I am going to demonstrate some useful postprocessing techniques using the “Marker” and “Graph Marker” subnodes. A very simple problem of acoustic scattering is used as an example, however, demonstrated postprocessing techniques can be used for any other physics. Click below to watch as I walk you through […]

Exporting High-Resolution Probe Data During a Parametric Sweep

Through experience, we discovered that if you want to develop an accumulated probe table, it doesn’t export the full resolution that you requested under “Updating probes.” So, in our latest Tips & Tricks video, I walk you through three steps you can take to export high-resolution probe data during a parametric sweep. Click below to […]

How to Develop Fly-Through Animations

Fly-through animations are a creative way to visualize inside 3-dimensional plots. In our latest Tips & Tricks video, I demonstrate how to develop these fly-through animations. The trick is, once you have your results stored in your data set, you need to define a results parameter that will be used to govern a filter of […]

Extending the Number of Characters Stored in the Log with COMSOL Version 6.1

In some cases, the information in the log file of a simulation is lost when the maximum number of characters in the log file is exceeded. In this video tip, we show how to increase the maximum number of characters to provide access to important data. To help you follow along, we have included the […]
